What can I do to avoid needing as any here?

Updates the typescript api to match
cd typescript-api
npm ci
cd ../tests
npm run setup-typescript-api

@notlesh you dont need to build any new types or api-augment pkgs, that's been done already.
All you need todo is update the api-augment package to 2301 which contains the updated interfaces (and removes the need for any locally for me at least)
in: moonbeam/tests
npm i @moonbeam-network/api-augment@latest
tests/util/block.ts
Outdated

Something seems very broken about dispatchInfo.weight. In this particular case (running test "should be able to calculate entire fee"), it's reporting a refTime of 423314000 which is definitely wrong.
The real value should be 173314000, which is correct in fee.weight. Why is dispatchInfo so wrong?

Furthermore, why is it used [presumably] correctly (above in the same fn) for Ethereum txns?

Shouldn't this be "debug" instead of console.log?

Heh, sorry. Removed in 316c698

You can replace this assertion value here is WEIGHT_FEE defined in constants.ts if you feel this is appropriate.
If not, feel free to define some constants in there with appropriate names which you want to assert against (which can then be reusable in other tests).

* Add minimal tests to show that new runtime API endpoints exist * prettier * WIP: trying to reassemble substrate fees * Basic fee calc works * prettier * Remove dead code * Prefer const over let 🙈 * Validate substrate tips properly (burned) * Remove console.log() * Use well-defined constant * Fix merge conflict 👀 * Remove as any * Reflect substrate tips being handled now 🎉 * prettier * Explain the length fee calculation * Use newly defined constant
What does it do?
This is the first pass at using the new
transaction-paymentruntime API added in Substrate.It will at least add test coverage demonstrating that the API works and how it can be used to calculate the entire fee for a Substrate-based transaction.
As a reminder, this was added so that we can run exhaustive tests around fee calculation, which we were doing until it broke in paritytech/substrate#11415 when it became impossible to know all fee parameters from a client alone.
